| Human hearing perception response is logarithmic. This is part of the reason we use the unit. Our senses naturally work in that domain. |

| > Human hearing perception response is logarithmic. It is, but -50db to -47db (+3db) is not double perceived loudness. It's double power. About +6 or even +10db would be double perceived loudness. |

| ▲ | hashhar 2 days ago | parent [-] | | Going from -50dB to -44dB is a much louder change than going from -6dB to 0dB. Human hearing is logarithmic. The dB is measuring ratio of sound pressure level and it's accurate that +/-3dB is almost doubling/halving of the SPL. | | |

-50dB to -44dB and -6dB to 0dB is the same change in power, as a factor. If human hearing is logarithmic, the same factor produces the same increase in loudness. |
